Y.,

A pairlof blocks 11 and 12, respectively, fit slidabvlygin the ends ofthe groove 7." The inner faces 13 of the said` blocks are disposed Y` obliquely with relation to one another, the v faces 13 being closertogether `at the `bottoni ofthe groove 7. A shoe 14 is interposed betweenthe blocks 11 and 12, the end faces 15V of the'said .shoe fitting the inner faces 13 of `the'blocks 11 and 12. `A screw 16 passes in i' :un threaded relation. through holes 17 and 18 inbloclrll and shoe 14,v respectively, a and threads into tapped holev 19 in the other block 12, thev head 2O of the screw bearing against' ithe outer face 21 .of the block 11.

Blocks. 11 and 12 and shoe 14 are preferably formed from cylindrical stock, a slice Vbeing taken from oneside of the stock to form a Y retracted-surface 22 tov accommodate; the

cylindrical surfaceV 23 ofthe shafty 2. Slice 14 is of smaller external diameter and of larger internal diameter than the blocks 11V vand 12,150 that, when the blocks are screwed toward one anotherbyturningthe screw 16 inthe proper. direction, clearance is afforded V `the shoe l14 for the ,resulting transverse movementof the said shoe toward the shaft 2 yby-'reason of the wedging action of the `mutuallyapproachingfaces 13 on the shoe 14. The engagement of surfaces 22 with the sh'aftsurface 23 prevents the blocks 11 and 12 and the shoe14 fromturning with the screw 16. Furthermore, the shoe 14 bears onthe shaft 2 with asu'rface 22 of extended area instead of exerting `pressure througha "mere line of contact, as would occur if there were no special surface 22 provided von theshoe 14 to .-fit'the Vcylindrical surface 23 l of tlie shaft 2. f

' yIt will be observed that with this arrange. lment v'no burs can be formed onV the shaft;

the. manipulation ofthe screw 16 does-'not yeisturb the preliminary setting ofthe roll '.11on the shaft 2 when it is desired to fasten ythe `rollA ony the shaft' after determining its Vi-zfcorrect position; the screw 16V is accessible fiioIn-.the end of the roll 1; and the shoe 14 bears on theiniddle portion of the embraced surfaceprofythe shaft l2, drawing .the flanges i Y 6 against the opposite side ofrthe shaft'2, and i securing the same in a4 stable fixed position,

'preventing any ,transverse 'rocking ofthe roll l1 on the vshaft 2 because Y y of highvspots or foreign matter thereon. i -V f Having thus'ffully'nrdescrib'edthis invenw tion, vI hereby reserve the benefit of all.
